.My device ounr'ls 'it-rally oi a mold Wall made preferably ol et incisi aurl .reinforced witlrangle bars, this we il beloouuule iu slioi" sectionsconnected bt" means oi .ri u" :xxl ending vertically through the oyes:u lapping coils on rho ingle bar 7.bereby' the devicbi may be adapted u buildings ol various sizes; supporting bars bjyubivll this 'wail is' bold in place when in use, 'bolts by wliiizln these supporting bars may be connect'- erl either to nu inner uiold wall loi' :forming Walls enf un ,irilinary bowlen building-j, whereby said. surface may be commi with concrete molded ou tlm outer" surface to uuu .c a concreto Wall, occasion may require, aud u. r1 e adapted lor use when leuning l1ol low Walls, unil i u various Features of combine-,tion and arrangement, u. Till more i'ully appear by reference to the accompanyuur drawin in which:

Figure l. :t perspective oi' my device arranged to opi"ormiug' Walls Wholly ol concrete; Fig. 2. a transverse seciFgz ll. an elevation o the core for torturing a hollow Wall; Fig. tl, au inverted plan View oi tbe suine; lfit a perspective illustrating tbe arrangement ol" uy device l'or costing the outer surface oi an ordinary wooden building; and, llig. ti. a trans verse section ot tbe salue.

Lillie numbr rotor to like parts iu all of tlie figures. o Wall of a. mold which Wall is prefer; "d slioet metall to lovin tlle concrete n [n e :i ltiurl oi Werl: in brick orstono, tlio :l sliou bei'ugg; a plain, ilat Wall with pointed scams. This Wold 4wall is preferably reinforced by means oi anglo bars 3 outentiing longitudinally of its outer euri-.lee suol secured thereto, and is made in short sections with tbe anglo bars prolonged beyond the ends of tlie sections und overlapped as at 1l and the sections secured cud to und by means of rods 5 extending vertically tlirouylx openings in the overlapped portionsoi attached to tbe outer surluce o` tbc angle bars. One section of this wall is made angw lar to extend'around tbe corner of a building and for tile purpose oi using'this mold to form Walls Wholly of cbncrete, an inner Wall 2 of any convenient material and construction may be used and the Wall l secured in place 'and spaced apart from the other Wall by means of supporting bars 7 and4 8 connected above and belowl the outer wall by bolts 9 whereby they are held. against the pressure of the material therebetween and adiusted for thickness of the concrete, the lower bolts ,lt extend through the )upper portion oi the part of tb'e Wall last formed and support the mold thereon as indicated in Fig. 2.

To form a chamber in the interior of the wall, provide a core consisting of two vertically corrugated sheets ol movement toward eachother, rods lll are jour'uale'cl in the bar ll and thel angle bar 13 and each provided with a cranlzmember 16 at its lower end.whicli,.engages tllcfbar l2, and also provided With'an eyeflfby which the rod is inanually rotated. When the pranks ltlare adjusted to hold tbs lower edges oi the 4plates l() apart,

the plates will be in parallel planes and when tbe rods lll are manually rotatedwith the crank 16 turned away from tbe bar 1 2, tlie plates will approach each other at "fthe lower edge, and can then be readily removed up .Ward from between the respective sides of the concrete Wall. This core can then be vertically adjusted and again separated at the bottom by turning the rods when the lriction of their lower portions against the concrete will sustain them in place While forming the next layer side `with a thin cement structure molded in imitay tion of stone work, or otherwise the Wall l is supported at any desired distance from the surface oi the build# 4lug by of shorter bolts or lag screws 9E iu place of the bolts 9, these bolts or screws being inserted in the wall of the Wood building which takes the place of the inner wall 2. To more securely retain this thin layer of concrete in place, I pre'ler tolapply to the building a wirenetting 19 secured thereto by nails or staples. However, this is not necessary; latli, nails or other suit able means of4 attachment .may be used. Obviously these molds are moved upward step by step as the work progresses, and the holes in the concrete formed by the bolts or lagscrews are What I claim is:

In a mold for hollow concrete walls, a. core comprising two corrugated sheet metal plates, a bei' to vwhich said if) plates ere aLmehed one of said platesbeing movable toward und from the other plate ab the 1ower`edge, supthe langle bars,A and bolts eeenee porting bars attached to the respective plates near the lower edges, a. rod jonrlmled in the upper bnr and in one of the lower bars, aerank member on the rod and engaging the other lower bar to space the plates npart at their lower edges, and means for manually rotating the rod.

In testimony whereof I alllx my signature in presence of two witnesses.
